On increasing of a quantity if the other quantity increases with the same price then they are straight proportional to every other. The authorize for directly proportional is ∝.If x is directly proportional to y then x ∝ y

Indirectly proportional:

On enhancing of a quantity if the various other quantity decreases with the same rate then lock are directly proportional to every other.If x is indirectly proportional to y then x ∝ 1/y

Further Explanation:

It has been provided that W varies directly with u and also inversely v d. So, native the above mentioned definitions, we have


Removing the proportionality sign and include a constant k


Therefore, the forced equation is

The equation is offered as W varies straight with u and inversely with d, climate the equation is composed as:W = k1uhere k2 is the proportionality constant.and ns = k2
here k2 is the proportionality constant.Thus, combining both equations us get, ns = K
where K = K1*K2, is the proportionality constant.

You are watching: W varies directly with u and inversely with d

MP = ns - M = (0, 5) - (5, 6) = (0-5, 5-6) = (-5, -1) |MP| = √((-5)^2 + (-1)^2) = √(25+1) = √26

Which is the value of y in the mechanism of equations 4x-5y=18 5x+y=58
kenny6666 <7>

Using equipment of equations, we require to get rid of one variable to do it into a 1 variable equation either using elimination or substitution.

Equation 1: 4x - 5y = 18

Equation 2: 5x+y = 58

For equation 2, there is just one y which makes it basic to substitute. So subtract 5x from both sides of the equation come get

y = -5x+58

Then we know what y is in regards to x, therefore plug it into equation 1.

4x - 5(-5x+58) = 18

It is now an equation with only 1 variable, i m sorry we can solve.

Distribute the -5 come (-5x+58)

4x+25x-290 = 18

Combine favor terms

29x-290 = 18

Add 290 to both sides

29x = 308

Divide both sides by 29 to isolation the x

x = 308/29 wow what one ugly number, however its alright

Plug in x to equation 2 to discover what y is

5(308/29)+y = 58

1540/29+y = 58

Subtract 1540/29 from both sides

y = 142/29

The y worth is 142/29

In 2 or much more complete sentences explain how friend would set up and also solve the equation: Dan and Rick belonging to various gyms. Da
olga55 <171>
The equation would be 40+15p=70+5p. You would certainly subtract 5p from every side (15-5) and also (5-5) and you"ll have actually 40+10p=70. You would certainly then subtract 40 from each side (70-40) and (40-40) to have actually 10p=30. You would divide by both the the sides by 10, you would finish up through p=3. P is price training. The factor you divide and also subtract on both sides is since you desire the month to it is in on one side and the price training on the various other side.
